Compilation warning about behaviour not existing.

Hi, I really appreciate this project and am using it where I can. I have run into an issue where I get a compiler warning (elixir 1.14.0-otp-25) about the generated behaviour not being implemented. ``` warning: @behaviour Service.Effects does not exist (in module Service.Effects) lib/service.ex:9: Service.Effects (module) warning: got "@impl Service.Effects" for function write/1 but this behaviour does not specify such callback. There are no known callbacks, please specify the proper @behaviour and make sure it defines callbacks lib/service.ex:13: Service.Effects (module) ``` Whilst this isn't problematic in itself (everything works), our CI compiles with the flag `--warnings-as-errors` so it fails. I have included a [effects.zip](https://github.com/user-attachments/files/17700985/effects.zip) but it doesn't deviate much from the examples in the readme. ``` defmodule Service do alias Service.Effects def write() do Effects.write("Hello, World!") end end defmodule Service.Effects do use Efx @spec write(String.t()) :: :ok defeffect write(value) do File.write!("/tmp/abc.txt", value) end end ``` Any help is greatly appreciated. Thanks Matt
